About Random Number Generator
Generate one or many random integers between a minimum and maximum (optionally with no repeats), flip a virtual coin with a running tally, or roll any number of dice with 4 to 100 sides.
Numbers come from the browser's crypto random source with rejection sampling, so the distribution is unbiased. Everything runs locally.
